Ritika Reddy 0a483618b9 KAFKA-19690-Add epoch check before verification guard check to prevent unexpected fatal error (#20534) ... We are seeing cases where a Kafka Streams (KS) thread stalls for ~20 seconds. During this stall, the broker correctly aborts the open transaction (triggered by the 10-second transaction timeout). However, when the KS thread resumes, instead of receiving the expected InvalidProducerEpochException (which we already handle gracefully as part of transaction abort), the client is instead hit with an InvalidTxnStateException. KS currently treats this as a fatal error, causing the application to fail. To fix this, we've added an epoch check before the verification check to send the recoverable InvalidProducerEpochException instead of the fatal InvalidTxnStateException. This helps safeguard both tv1 and tv2 clients Reviewers: Justine Olshan <jolshan@confluent.io>		2025-09-23 13:45:42 -07:00
